Synthesis of trimethylolpropane trioleate by using stannous oxalate catalyst

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study was conducted to synthesize trimethylolpropane trioleate (TMPTO) using a stannous oxalate catalyst and investigate the dependence of the esterification rate on reaction variables. The highest esterification rate of approximately 99% was achieved at a 2.75:1 oleic acid/trimethylolpropane, 1.5% catalyst amount, 180°C reaction ...

Life cycle assessment of biodiesel synthesis from waste cooking oil using bifunctional heterogeneous catalyst

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The development of renewable energy sources is important in order to achieve the United Nations Sustainable Development Goals (SDGs). Waste cooking oil (WCO) is a promising feedstock for biodiesel production through transesterification. Heterogeneous bifunctional catalysts offer a sustainable alternative to conventional homogeneous bases such ...

Ocrelizumab‐induced colitis: VigiBase disproportionality analysis, case reports and literature review

British Journal of Clinical Pharmacology, EarlyView.
Aims Ocrelizumab is a humanized anti‐CD20 monoclonal antibody used in multiple sclerosis. Since its commercialization, several cases of ocrelizumab‐induced colitis have been reported in the scientific literature. Methods To explore the potential association of ocrelizumab with colitis as an adverse drug reaction (ADR), we conducted a descriptive and ...

‘School is their whole world’: Teachers' perspectives on loneliness among children and adolescents from England and mainland China

British Educational Research Journal, EarlyView.
Abstract As front‐line observers and active participants in pupils' daily lives, teachers closely monitor pupils' social interactions, emotional states and behavioural changes. Their unique perspective enables them to detect problems in the social lives of their pupils that may not be immediately visible to peers, parents or mental health professionals.
